Positive margins were found in 12.2% (22/180) of all tumors, 12.5% (8/64) of supraglottic tumors, 16% (4/25) of transglottic tumors, 5.3% (2/38) of glottic tumors, 11.1% (2/18) of pyriform fossa tumors, 50% (3/6) of posterior pharyngeal wall tumors, and 10.6% (3/29) of postcricoid tumors. The relationship between the inadequate surgical margins of the specimens, tumor spread, preoperative CT findings, and surgical procedures performed have been correlated.

In the TLM group, different subtypes of type V cordectomy were used according to the extent of tumor. In the vertical hemilaryngectomy group, classical operation was used in most of the cases and the resection was extended in few cases. Analysis of post-operative swallowing function was done using videofluoroscopy (VFS), functional endoscopic evaluation of swallowing, and subjectively using MD Anderson dysphagia inventory. Objective evaluation of swallowing has been made by obtaining different measures from VFS (pharyngeal transit time, pharyngeal constriction ratio, and hyoid displacement for example). Analysis also included the need and duration of tracheostomy and nasogastric tube, ICU admission, and hospitalization time. Statistical analysis was performed with the Mann-Whitney U and Pearson Chi-square tests. Comparison of incidence of aspiration and swallowing outcome showed significantly better results in the laser group than in the vertical group (p < 0.001). The duration of ICU, tracheostomy, nasogastric tube, and hospital stay was also significantly shorter in the laser group (p < 0.001). This study shows that TLM had significantly better overall postoperative outcome than vertical hemilaryngectomy. It was associated with significantly shorter hospital stay and less need for tracheostomy, nasogastric tube, and ICU admission). Measures obtained from VFS are useful for detection and follow-up of postoperative aspiration, because it is a definitive technique for anatomical and physiological study of swallowing.

The relationship of the sphenoid sinuses to the carotid artery, optic nerve, floor of sella turcica, as well as other important structures, were verified and discussed. The recesses of the sinus as well as its ostium and accessory septa and crests were described and their clinical importance was discussed. Pertinent measurements were included wherever appropriate.

Permanent irreversible changes, in the form of parakeratosis and squamous metaplasia of the epithelium, and hypertrophy of the muscle fibers, were observed together with persistence of increased alkaline phosphatase enzyme intensity in the endothelium of capillaries and increased activity of nonspecific esterase in the muscles. Similar changes may be responsible for the alteration in the human female's voice after prolonged treatment with anabolic steroids.

Eleven patients (68.75 per cent) had twelve carotid paragangliomas (CPs), and five patients (31.25 per cent) had six vagal paragangliomas (VP). One CP (8.33 per cent) originated from paraganglia around the common carotid artery (CCA). Three cases of multiple paragangliomas are presented (18.75 per cent). In 80 per cent (4/5) of VP patients there was widening of the carotid bifurcation similar to that seen with CP. This widening occurred whenever the VP was large enough to grown in between the external carotid artery and internal carotid artery (ECA and ICA). Large VPs may displace the vessels either anterolaterally or anteromedially. Knowledge of the direction of the carotid displacement is essential to avoid intra-operative vascular injuries. Colour flow doppler ultrasound (CFD-US) was found to be a good non-invasive method for diagnosis of vascular neck swellings. It enabled the diagnosis of CP with 100 per cent accuracy, but it was not sufficient for diagnosis of high VP. A transcervical approach, cutting the digastric muscle and the styloid process with the attached ligaments and muscles, was sufficient for excision of most VP. However, midline mandibulotomy might be necessary with high VP. Vascular injuries occurred in 12.5 per cent (2/16) of patients. Superior laryngeal nerve and hypoglossal nerve paralysis occurred, respectively, in (2/11) and (1/11) of patients with CP. Vagal paralysis occurred in all patients with VP. Cerebrovascular accident and post-operative death occurred in one patient (6.26 per cent).

This fact when combined with the recent advances in preoperative imaging diagnostic modalities and intraoperative identification of the diseased gland has allowed the development of minimally invasive endoscopic assisted parathyroidectomy (MIEAP). Objective: Treatment of patients with primary hyperparathyroidism due to a single gland disease, with minimally invasive endoscopic-assisted parathyroidectomy. Subjects and methods: Nine patients (seven females and two males) with PHPT were proved to have a single-gland parathyroid adenoma after preoperative imaging techniques. They were scheduled for MIEAP, with intraoperative identification by MB. Results: Surgical time ranged between 21 and 35 min through a small surgical wound and cure rate of 100% with no recorded complications.Conclusion: MIEAP is an easy, safe and effective maneuver for management of PHPT due to a localized adenoma. It is less costly with a cosmetically-accepted wound.

They are frequently inadvertently placed by children in their ears or noses and occasionally are swallowed and lodged along the upper aerodigestive tract. The purpose of this work is to study the different presentations of button battery foreign bodies and present our experience in the diagnosis and management of this hazardous problem in children. Patients and Methods. This study included 13 patients. The diagnostic protocol was comprised of a thorough history, head and neck physical examination, and appropriate radiographic evaluation. The button batteries were emergently extracted under general anesthesia. Results. The average follow-up period was 4.3 months. Five patients had a nasal button battery. Four patients had an esophageal button battery.Three patients had a button battery in the stomach. One patient had a button battery impacted in the left external ear canal.Apart froma nasal septal perforation and a tympanicmembrane perforation,no major complications were detected. Conclusion. Early detection is the key in the management of button battery foreign bodies. They have a distinctive appearance on radiography, and its prompt removal is mandatory, especially for batteries lodged in the esophagus. Physicians must recognize the hazardous potential and serious implications of such an accident. There is a need for more public education about this serious problem.

Classically, it presents as an anterior midline neck swelling that moves with deglutition and protrusion of the tongue. Occasionally, thyroglossal duct cyst presents in atypical manner either clinically or radiologically, which may pose a diagnostic challenge. Objective: The aim of this study is to review cases diagnosed with thyroglossal duct cysts as regards clinical and radiological presentation, focusing on cases with atypical presentation. Patients and methods: The medical records of patients who were diagnosed with thyroglossal duct cysts from January 2004 till October 2007 were retrospectively reviewed. A total of 22 patients were included in the study. They were classified as typical and atypical according to the clinical and radiological presentation. Results: There were 10 males (45.5%) and 12 females (54.5%) with mean age of 17.3 years. The site of the cyst was infrahyoid in 20 cases (91%), suprahyoid in one case (4.5%) and intralingual in one case (4.5%). Clinically, 16 cases (72.7%) showed typical presentation and six cases (27.3%) were atypical in the form of: thyroglossal duct cyst with intralaryngeal extension, intralingual cyst,ruptured cyst with subsequent chronic inflammatory changes within the anterior neck compartment, thyroglossal duct cyst with intracystic solid mass, inferiorly located cyst that was mobile with deglutition but not with tongue protrusion, and thyroglossal duct cyst presenting as lateral neck swelling. Radiologically, T2 weighted magnetic resonance imaging was the only radiological modality that showed a tract extending to the tongue base. Conclusion: Thyroglossal duct cyst should be considered in the differential diagnosis of any anterior neck swelling. T2 weighted magnetic resonance imaging is the most informative radiological modality. It can be used to differentiate cysts with atypical presentation from other neck swellings.
